Hayao Imagawa, a 30-year-old office worker, grapples with profound social anxiety and inexperience in romance, leading him to seek solace in an inflatable doll—a silent companion underscoring his resigned acceptance of isolation. His stagnant existence shifts when celestial forces intervene, steering him toward confronting his virginity through exercises in communication and self-assurance.

With black hair trimmed neatly at ear length, black eyes framed by glasses, and a timid demeanor marked by a tendency to shrink from confrontation—particularly around women—Hayao embodies hesitant vulnerability. His path intertwines with a shy librarian equally unversed in romance, their tentative bond blossoming through shared insecurities and guidance from unorthodox divine mentors who craft bizarre scenarios to mirror real-life challenges.

The narrative delves into his struggles against societal pressures dictating adult masculinity, balancing absurd humor with heartfelt stumbles through dating rituals, intimacy, and the pursuit of self-worth. Pivotal moments involve facing rejection, mastering earnest romantic overtures, and grasping the nuances of consent. While his profession as a salaryman anchors his routine, the story prioritizes internal battles over external ambition.

Hayao’s arc culminates in gradual steps toward authentic relationships, prioritizing the jagged process of growth—awkward missteps, fleeting triumphs, and fragile hope—over a neatly tied resolution.
